Safe-PakTM Installation Instructions: CFM 3156
Thank you for your purchase of the Safe-Pak for the CFM Model 3156 vacuum system. Please be sure to read these instructions thoroughly before operating the 3156 vacuum in conjunction with this Safe-Pak Kit.
WARNING: This Safe-Pak Kit is designed to be used for the collection of dangerous and potent materials. It is the responsibility of the end user to comply with all of the applicable procedures mandated for the specific material that is being handled. Proper disposal must also comply with local environmental and safety procedures.
Checking Phase Rotation of the Vacuum:
The first and most important step in using the Safe-Pak is to make sure the rotation of the motor is correct so that the vacuum will draw air into the inlet rather than blowing air out.
WARNING: It is important to check this rotation prior to each use of the Safe-Pak. Any collected debris within the Safe-Pak could be blown out of the container if the rotation of the vacuum motor is incorrect.
To check the rotation simply wire the vacuum to the appropriate electrical source by either using a quick connect electrical plug, or by hard wiring the electrical cord to an electrical circuit. A licensed electrician must perform this operation.
Once this is complete, simply turn the vacuum unit on by turning the red radial switch (Photo 1) in the clockwise direction. The on (‘I’) position of the switch is at 12 o’clock, while the off (‘O’) position is at 9 o’clock.
Once the machine has been turned on you will be able to tell if the vacuum is in the proper rotation by placing your hand over the exhaust tube (Photo 2). If your machine has a downstream HEPA filter, the air will exhaust from the area shown in Photo 3.
If you detect that air is blowing out from either of these two places, then the vacuum is in the proper rotation and is ready for further preparation for use. If you do not detect air exhausting from either location pictured in Photo 2 or 3, then the vacuum motor is rotating in the reverse direction and needs to be corrected.
This phase rotation problem only occurs when dealing with motors running on three-phase electrical power. If you have a vacuum system that is running on single-phase power the rotation problem should not occur. However if you detect that air is not exhausting properly from the locations pictured in Photo 2 or 3, please contact our Customer Service Department at 1-800-NILFISK.
